PROBLEM TO BE SOLVED: To provide a low-cost thermal head with high productivity, which reduces unevenness in printing density and which can be applied to high-speed printing, a manufacturing method therefor, and a thermal printer. SOLUTION: In this thermal head, a head substrate 1 with a heating element 4 is placed on a radiator plate 7; a resin material 8 is interposed directly below the heating element 4 in areas between the radiator plate 7 and the head substrate 1; a double-faced adhesive tape 9 is interposed between other areas; surface roughness on the radiator plate 7, which is brought into contact at least with the resin material 8, is set to be an arithmetic mean roughness Ra of 0.24-0.5μm; and the surface roughness of a head substrate surface, which is brought into contact with the resin material 8, is set lower than the surface roughness on the radiator plate 7.
